Abstract

An emboli capturing filter device and system are provided. The filter device includes an expandable filter disposed about an elongate member. The filter has a proximal mouth portion facing the proximal end of the elongate member, and a distal portion extending toward to distal end of the elongate member. A support arm is coupled to the elongate member and mouth portion of the expandable filter. When the filter is in an expanded orientation, the support arm is attached to the elongate member at or distal of the mouth of the filter.
